Spanish speaking Audiogoners?

I sold a pair of interconnects a few months ago on Audiogon to a gentleman from Argentina. His English skills are minimal, and my Spanish only slightly better than that, but we got through the transaction with the help of dictionaries and translation software. I've just had an email from him that he'd like to post some of his gear on Audiogon, but needs an explanation of how selling on the site works. Is there any kindly Audiogoner who writes fluent Spanish who would be willing to help out? Please identify yourself on this thread, or by email directly to me, and I'll forward privately his email address. Thanks!
